Definitions

  • the invention relates to an RF module, e.g. a tuner, with a case and with a printed circuit board mounted in the housing and carrying electrical components, wherein the housing is trough-shaped and closed with a lid.
  • RF module e.g. a tuner
  • Housings for such tuners are known, each housing together with Partitions for a printed circuit board accommodated by the housing made from one piece is. Such a housing is closed by two lids. With such a Housings become the ground points for the circuit board on the housing walls prefabricated partitions. The location of the earth points is therefore on the Area of the partition walls limited.
  • each housing consists of a frame, one each special use with partitions for the circuit board and consists of two lids. Overall, four individual parts are required for such a known housing.
  • DE 35 35 923 A1 is a substrate-holding structure for a multilayer printed circuit arrangement become known, with a metal plate between two Printed circuit substrates is arranged.
  • the metal plate has tongue-like Segments that are bent such that they are formed by in the circuit substrates Holes can be passed through, so that conductor tracks on the outside lying surfaces of the circuit substrates can be grounded to the metal plate.
  • the metal plate is in the outer edge area with connecting segments connected to a chassis in a resilient manner.
  • US-A-5,434,747 shows a housing in which conductive stator parts and Contact pins are only arranged in a line on the edges of the housing, the stand parts mainly serve as a holder for a printed circuit board.
  • the Ground contact is made via the contact pins of the stand parts.
  • the invention is based, an RF module of the type mentioned in the task To simplify construction and with regard to optimal use of space on the circuit board to improve.
  • the contact pins at the ends are tapered in stages. This results in attacks, so that the Insert can easily be put on and soldered.
  • a simple structure also results from the fact that the use in further Embodiment of the invention is designed as a ground plate and that the contact pins are formed on the mass plate by punching out and right-angled kinking.
  • the contact pins on can also be attached to the insert by soldering.
  • Another embodiment of the invention is that at least part of the Contact pins is formed so long that this in corresponding openings of the Engage the cover and are fastened there by clamping or soldering. So that is an optimal ground connection between the housing (frame), the insert, the Printed circuit board and the lid ensured, which makes for very good RF shielding is guaranteed.
  • FIG. 1 an embodiment of the object is in accordance with the figure the invention is shown schematically and in perspective.
  • the figure shows in one exploded view of a tuner with a trough-shaped housing, an insert, a circuit board and a lid.
  • the trough-shaped housing 10 is e.g. stamped from a one-piece sheet metal part and brought into the tub-like shape by kinking. In addition, a Solder on the abutting edges.
  • Printed circuit board 11 attached, which is equipped with schematically indicated components 12 is. With 13 pins are designated.
  • the circuit board 11 has ground points 14, which are provided with holes.
  • 15 denotes a metallic insert, which is provided with contact pins 16 bent at right angles. The location of this Contact pins 16 depend on the position of those attached to the printed circuit board 11 Earth points 14. The ends of the contact pins 16 engage in the assembled Condition in the holes or ground points 14 of the circuit board 11 and are with soldered this.
  • the circuit board 11 soldered to the insert 15 is after Completion inserted into the trough-shaped housing 10 and fastened there. Thereafter, the housing 10 is closed by a cover 17, the resilient Tabs 18 is provided. As can be seen from the figure, the mass points 14 may be provided at any point on the circuit board 11, where appropriate Space is available.
  • a part of the contact pins 16 can be so long that they in corresponding openings 19 of the cover 17 engage. This results in an optimal one Earth connection between the housing (frame) 10, the insert 15, the Printed circuit board 11 and the cover 17 and thus very good shielding.
